The program performs Newton-Raphson-based power flow analysis on a test system with 26 buses. It constructs the admittance matrix (Y-bus), initializes bus and line data, and iteratively solves nonlinear power equations using Jacobian-based updates. It enforces generator reactive power limits and computes mismatches until convergence.
Post-convergence, it calculates branch power flows and losses in both directions and aggregates system-wide losses. The script outputs numerical results and generates visual plots of bus voltages, bus voltage deviation indices (BVDI), voltage angles, and active/reactive power losses, aiding in assessing system stability and efficiency.
